Manufacturer: Pearl Model Number: T-072 Total Length: 123mm Length Under Head: 105mm Threaded Section: 31mm These are slightly older Pearl tension rods. There are 16 rods, enough for one 8-tension bass drum (both sides). They are all in good condition, with no significant rust or noticeable scratches. They are in working condition. I am also selling new T-072 rods (10 pieces) at the same time, so please take a look.
